And matching impedance with amps is fairly simple when only using one or two subs. But it becomes more complicated as the number of subs installed increases. Amplifiers power subwoofers. And the amount of power that a subwoofer can handle is represented in peak watts for peak power handling and Root Mean Square RMS watts for continuous power handling.
Peak power handling is the maximum amount of power a sub can handle without getting damaged. Amps have an RMS watt range rating, referring to the minimum and maximum power ranges produced by the amp. To ensure your car stereo system has excellent bass, you need to find an amp that matches your sub. Estimated wait for next available agent :.

For Tech Support, call I belong to a culture of fine sights and sounds, and I like spreading the word. I've been tinkering with electronics ever since I was a kid - starting with taking apart and putting back together televisions and radios.
I always got them back together again and working. I took courses in radio and electronics as a teenager, and became a ham radio operator. I worked in my high school's stage crew, running sound, lights, and a movie projector. After college, I joined a rock 'n roll band as the soundman and learned how to lug around and operate the gear that helps make music sound good and loud.
Working in a music store in Austin, Texas, I spent a few years manufacturing, installing, repairing, and operating sound systems. Our customers were recording studios, nightclubs, and touring bands. Eventually I moved back to Charlottesville, Virginia and opened a small demo recording studio. In , I finally came to my senses and got this job at Crutchfield. They actually pay me to ramble on, rant, and explain the things I love about music, electronics, and getting good sound.
Given my background, they put me to work writing about some of the most complex electronic products Crutchfield sells: car amplifiers, digital signal processors, wiring, professional sound mixers, and PA systems.
The secret to great bass is making sure your subwoofers and amp are evenly matched and will properly work together.
And this article will help you figure out how to do just that — match amplifiers and subwoofers. Getting the right sub for an amp, or the right amp for a sub, is like solving a puzzle.
A subwoofer has impedance measured in ohms which represents the "load" an amplifier will sense on its output. An amplifier will put out different amounts of power watts RMS based on the impedance load it "sees.
Your goal is to get those two variables to match for both the amplifier and the subwoofer. Below, we cover the important basics of power-matching, impedance, and planning for the number of subs you want, and we approach the situation from both sides of the system:. Part A — You have the subs, which amplifier should you get?
Multiple subs wired together must be the same coil type and impedance. If you want to run different types of subs in a system, each type needs to have its own separate amp. Figure out the possible total impedance s that the subs can be wired together to form. For more combinations of subs and their impedances, see Subwoofer Wiring Diagrams. Using the chart in Step 2, 2 DVC 4-ohm subs can be wired together to form a 1-ohm, a 4-ohm, or a ohm load.
Any one of these high-quality amplifiers would work well with those subs. Part B — You have the amplfier, which subs should you get? Divide the power you picked in Step 1 by the number of subs you want. Using the impedance you picked in Step 1 and the number of subs from Step 2, cross-reference the possible coil configurations that you can use:. Look for subs that are rated at the wattage you figured in Step 2, and are configured as you found in Step 3.
This might sound confusing, so let's walk through an example and it'll make sense. This means your subs have to be wired to form a total impedance of 2 ohms. Using the chart in Step 3, for two subwoofers, a final 2-ohm load can be achieved with either two SVC 4-ohm subs or two DVC 2-ohm subs. All these subwoofers will sound their best when amplified with the proper amount of power.
Differences in size have more to do with tonal qualities and frequency response than with power performance. And optimizing performance is the point of matching subs and amps together. Part C — You have neither amp nor sub, and want help deciding how to begin.

I say all of this, because I'm nervous I could have damaged my brand new sub Less than 2 months old and after I was playing the music decently loud and smelt a scent of burning and then the amp cut-off which lead to no power to my sub.
I have a bigger amplifier that can handle the sub, I just haven't had the time to install it. I was planning on doing it within the next week but now I'm praying I didn't damage my sub-itself during the process. Hello, first I would like to note that I am noob in the audio branch.
I am looking to slightly improve the bass of my BMW. I have also purchased an amplifier for them, with specs: Two channel amp with maximum exit output of W, 2x55W at 4Ohms, 2x85W at 2Ohms.
I want to know if i had made a good choice, as once again saying I am total noob, just had a really good offer for them. Looking forward for you reply. I have 3 boss 10 inch subs four ohms what would be ideal to push these speakers and I have a five channel watt brigable amp can that be used with those speakers?
I bought it with the box and wasn't sure if it could be used? I'm hoping you can help with my set up. Confused on how to tune the lc2i and amp. I have 1 pair of wires coming from the subs, how should I connect them to this amp? What should the lc2i be set to? Amp looks like 6v max? From there any insight on how to tune the amp? Utility - Are you using your subwoofer as an attachment to your computer, as an auxiliary to a home theater setup, or as a supplement to your car stereo system?
The receiver of each stereo system might not accommodate a subwoofer output, a problem that can be easily solved with the purchase of a set of speaker cables.
Amplifiers can be difficult to source because many of us are unsure when it comes to configurations and impedance. Add to that a whole bunch of confusing jargon and you quickly find yourself in way over your head. To clear things up, we are diving into speaker amplifier terminology. This should help you read through the marketing spiel and find exactly what you need.
This gives it the ability to cope with the wavering between full-conduction and non-conduction, giving it an ultimately better output power and efficiency. The power construction resembles a 'V' shape and is also sometimes referred to as a V-set or V-Mosfet. They first came into commercial use during the s and have a few advantages. They are faster working, with more power, and their transit frequency is better.
This means they require a simpler form of short-circuit protection and are less likely to breakdown or fall prey to secondary problems. They handle higher transient currents better, without Beta droop the biggest cause of distortion from current draining and rely on much smaller sized driver transistors to function.
This means they can be used within smaller applications. They also switch devices off more rapidly which eliminates crossover distortion. RMS stands for route mean square, a mathematical calculation of the mean the average found by dividing the sum of numbers by the total number of terms of a set of square numbers. Simply put, this describes the maximum peak level of output power that an amplifier can produce in a single split-second, for the loudest part of a song.
This doesn't refer to the maximum constant output power which will typically be much lower. You may have noticed that amplifiers are classified with one or 2 letters but you might be surprised to know that this doesn't define them best to worst or vice-versa in alphabetical order. This is because they aren't actually a grading system. The letters instead are a reference to how efficient their wave functionality is.
All amplifiers conduct through wave-forms. A class A amplifier conducts throughout degrees of a wave-form. This means in a single-ended design they are less likely to have a background hum as distortion levels are reduced. An A-class amplifier essentially requires a high-level current flowing continually even when there's no output power in the process.
This gives you quality audio, which is why they're often raved about by those with an appreciation for audio quality, but this unfortunately means that they have to conduct at all-times. Conducting continually leads to high amounts of wasted energy which is converted into heat. The build-up can cause over-heating issues. The circuitry for an A-class amplifier also requires a much larger chassis comparatively.
This is more efficient with less wastage but it does create a nominal delay between the two amplifiers. There are also G and H class speakers which we will skip-over as they are irrelevant to this particular article. D-Class amplifiers are the most efficient on the market and therefore arguably the best. This is because they can rapidly fluctuate the devices connected between an on and off state.
Having the ability to idle allows power consumption to be fully utilized optimally. They can provide much higher-outputs because of their design specs and are also less susceptible to over-heating issues. They are also able to be contained in a much smaller enclosure, making them a compact option and giving you more choice and freedom over where to install them in your car.
You can't install a subwoofer without the correct amplifier for the job, a mono-block single-channel addition is a sensible solution and fortunately, there is an abundance of capable models to choose from.
Finding the right amplifier for your subwoofer can be tricky if you aren't down with the lingo, we hope our guide, though heavily technical, will have shed some light on the subject. And hopefully, you'll find the right audio system for you. If you are unsure you can check the web for some DIY installation guide videos and if needs be, enlist a professional to do it for you, ensuring you get the best audio system.
